Main Article Content



In this work, considering a jet of air from the aside slit; scope is the air jetting onto the fluids contained within the container; the control volume is constructed. This wall bounded closure is simulated after meshing for various situations and jet path shows several flow zones. For empty system the jet shows turns and returns along the walls which elucidate the bubble formation and air trap positions. When the system is put with fluids compositely, in a half space, the layers are formed which may define the zone rising or flowing down with jet regimes. Gaseous mixture striding waves are observed too. Different levels of mass transfer are identified at interfaces and zones are isolated. These aftermath numerical practicals show the way to explain many operations during processing.

Fluid flow, jet, mixture waves, bubble positions, mass transfer.
